...I know who you are. Anyways, in case you aren't who I think, everyone must know I absolutely ADORE Toukasa noncon, they truly made my mind function differently after I first drew them for the nsfw week. And what I love the most is how unique their fucked-up dynamic would be. I really can't see Touya being aggressive and rash with his personality, but if we just keep his canon personality and take his admiration for Tsukasa to the next level, we get Yandere Touya, the creator of gentle rape, and that is simply... NGGHHHGGGHGG MWAH!!! I LOVE IT!

He would invite Tsukasa over to his house, and Tsukasa would think nothing of it, oblivious to the fact that he will never get out of there! Touya would sedate him with a drink and take him to a room he had prepared especially for his beloved senpai, where he would live from now on, full of the things he loves, but also, he has to maintain him being obedient and docile, so he's tied up and chained!! Tsukasa then wakes up to his kouhai fingering his little virgin pussy on a bed where he's half naked and spread out, lots of lube being poured in between his legs that make the squelching of his fingers thrust oh, so obscene to his ears.
He would trash and squirm and try to yell through his gag asking what is Touya doing, or even if he's okay because his inofensive kouhai would never do this. Touya cooes and shushes him. He's a little nervous seeing his senpai like that, but he starts thinking that maybe it was because Tsukasa just felt so good that he didn't know how to express it, so Touya kept moving his fingers in and out, deeper and deeper, faster and faster. Tsukasa would scream louder, but also moan from the forced pleasure his body is receiving, never having felt anything like this before, until he can't hold himself back anymore and comes, his thighs twitching and soaking wet with his own bodily fluids at the end. Touya stands still and kisses his senpai's soft temple, though covered in tears and sweat, and whispers to him that they can continue now, to finally be one.

Needless to say, Touya fucks Tsukasa thoroughly and relentlessly. After years of pent up, one sided feelings, he completely relishes again and again in the sweet sensation of taking his adorable senpai and having him all for himself... forever.
